TYPICAL APPLICATIONS
The signal sent by the Keyfob transmitter can be
received by the LR Series receiver module or the LT
Series transceiver module. The outstanding sensitivity
of the LR Series receiver offers the best range when
used with the Keyfob transmitter. The receiver module
is then connected directly to the MS Series decoder,
which will decode the transmitted signal.
When a button is pressed on the transmitter, a
corresponding line on the decoder will go high. This can
then be connected to external circuitry to perform
whatever function is required by the application.
The decoder must learn the transmitter’s address
before they can work together. This is done by taking
the LEARN line on the decoder high, typically with a
RXM-***-LR
LICAL-DEC-MS001
pushbutton. The MODE_IND line will start switching (if a LED is attached, this
will cause it to flash) indicating that the decoder is in Learn Mode. Press any of
the buttons on the transmitter to initiate a transmission. Take the LEARN line
high again to exit Learn Mode and the system is ready for use. The figure below
shows a schematic for a typical application.
The Keyfob is set to 9,600bps,
so SEL_BAUD0 should be tied
high and SEL_BAUD1 tied low.
The decoder has several unique
features, such as Latch Mode,
Receiver Control, and TX_ID.
If the LATCH line is tied to V CC ,
the outputs will go high on the

so the outputs will be momentary

received instructing the decoder
to make them high).

figure shows it tied to ground, but to use this feature, connect the RX_CNTL line
of the decoder directly to the receiver’s PDN line.
The TX_ID line will output a number associated with the originating transmitter /
encoder. Application Note AN-00156 shows how to use this feature.
